The Baby's Breath™ addresses the complete spectrum of air cleaning, removing sub-micron particles, noxious gases and chemicals. Every minute, The Baby's Breath™ draws over 125 cubic feet of air through a 4-stage HEGA filter containing Activated Military Carbon Cloth and over 30 square feet of True Medical Grade HEPA. The result, more clean air delivered faster and more efficiently than any other air cleaner on the market. (Junior units do not come standard with wheels but as an upgradable option.)
